Extracts of tomatoes and potatoes as biopesticides: a review

Pest control is crucial to protect animals and plants in the agriculture industry. Biopesticides, because of being environmentally friendly and renewable, have attracted more attention in recent years. Nonetheless, due to costs, issues with controlling pests across various agricultural methods, and supplementary obstacles, biopesticides constitute a minor portion of the worldwide market for crop protection. Agricultural products like tomatoes and potatoes stand as examples of Solanaceae, a significant plant family with numerous economically vital species. From 2022 to 2027, the tomato market is anticipated to have a Compound Annual Growth Rate (CAGR) of 5.6%. Likewise, the worldwide market size for potato starch is predicted to attain a value of $4.9 billion with a market growth of 3.5% CAGR by 2027. After harvest, tomato and potato by-products such as leaves, peels, stems, and so on are generated as by-products, but they have not been effectively utilized. Recent research studies show that extract of the byproducts contains components such as glycoalkaloids, flavonoids, additional phenolics, ketones, and so on, which can be used as biopesticides. For proper pest control and utilization of the by-products in agriculture and related industries, this paper provides a review of recent progress on the research of the active components in the extracts of agricultural by-products of tomato and potato, their roles for pest control, extraction methods, challenges, its future development, and more.
